TYPE-CASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 413,550, dated October 22, 1889.

Application filed December 29, 1888- Serial No. 295,111. (No model.) i

zen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Type-Casting Machines, which improvement is fully set forth in the followin g specification and accompanying drawings.

My invention consists of improvements in type-casting machines, more particularly designed for quads and spaces, the distinctive feature of the same being hereinafter set forth and. definitely claimed.

Figure 1 represents a partial side elevation and partial vertical section of a type-casting machine embodying. my invention. Fig. 2 represents a top or plan View thereof. Fig. 3 represents a vertical section on lines 00 00, Figs. 1 and 2, on an enlarged scale. Figs. 4 and 5 represent vertical sections respectively on lines y y and z z, Fig. 2,0n enlarged scales. Fig. 6 represents a horizontal section of the casting-chamber and intermediate parts on an enlarged scale. Figs. 7 and 8 represent side views of the means for cutting the jet from the type.

Similar letters and numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the frame of the machine, and B designates a shaft mounted thereon, and receiving power from any suitable source. To said shaft B are secured cams 1 2 3, the cam 1 being adapted to engage with a roller 4:, which is connected with an arm 5, depending from a slide 6, the latter being sustained on the upper part of the frame A and arranged in horizontal posiu tion, it being seen that said slide is advanced or moved in one direction by the operation of the cam 1. The slide 6 is provided with a pin projection or arm 6, which enters a socket 6 in the frame, said arm 5' serving as a guide for the slide. The return or opposite motion of the slide is occasioned by a spring 7, which encircles a rod 8 on the outer end of the slide and bears against the frame A and a nut or shoulder 9 on the rod, so that as the slide advances said spring is compressed, and when the cam 1 clears the roller 1 the spring becomes operative and exerts its pressure on the rod, as is evident. The slide carof an upper and a lower section or wall, each of-which is formed with or secured to said bed. The opening between the upper and lower walls of the mold forms a casting-chamber 13, having at one end the end of the slide when the same is in normal position, the walls of the sides and the other end of the chamber being formed as hereinafter described.

In order to steady the mold,I provide bolts or screws 14 15, one of which bears against the top of the same and a proper part of the bed 12, and the other is fitted to the bottom of the mold and bears against a proper part of the frame. From this construction it will be seen that the mold is formed of a block or piece of material with a channel therethrough, and that the same is secured to the frame by suitable means; and it will also be understood that one of the screws passes through the frame and engages one end of the mold, and the other passes through the mold and engages the frame, the screws serving to steady each end of the mold or distribute the strain on the mold evenly. On the side of the mold opposite to the plunger 0 isa slide E, which is guided in vertical direction in a proper part of the frame A, and which in normal position has its upper end coincident with the lower wall of the casting, the side of the slide E toward the mold forming, when the said slide is raised, the side of the said chamber 13 opposite to the plunger. lower end adapted to rest on a stop 16, and above said end is an opening 17, which receives a ball 18, through which freely passes a rod 19, projecting from the adjacent end of the lever F, which latter is mounted on a bracket or bearing-piece 20', it being seen that said lever and slide are connected by a balland-socket joint, as at 17 18. The end of the lever opposite to the slide E is adapted to be engaged by the cam 2, whereby when said latter is operated the slide is raised so that its upper end is caused to close the adjacent side of the casting-chamber. As the slide The slide E has its against the ball 18 and the head 22 of the which is to force said slide toward the mold D. Bearing against the side of said slide is a spring 26, which forces said slide toward the side plate 27.

G designates anipple for feeding the molten metal to the casting-chamber, the same having its discharge end in the plate 27 and in communication with the throat-plate 28, the throat of said plate being in communication with the one end of the casting-chamber 13. The other end of said chamber is closed by the wall 29 of the mold.

On the back of the slide E is a projection 30; or there may be fastened a block having an inclined face, which, when said slide rises, rides on the inclined face of a block 31, secured to the frame A, so that said slide is forcibly pressed against the mold for tightly closing the casting-chamber. The block 31 may be adjusted by means of a screw 32, which is fitted in an ear 33 on the frame A and bears against said block.

H designates the table for receiving the type as cast after leaving the mold, the same being coincident with the bottom wall of the casting-chamber and top of the slide E when the latter is in normal position, it being seen that the plunger C is of such length that it may pass through the mold, move over the top of the slide, and fully reach the table in order to eject the quad, &c., as cast from the mold and direct it upon thetable. Above the table is a plate 34, which'is hinged to a plate 35, said plate being raised above the table, so that the type may pass under the same, the plate 34 being gently forced down bya spring 36, whereby the type are prevented from rising or being moved with irregularity on the table. Between the plate 35 and the table H is a plate 37, which serves to keep said plate 35 separated from said table, forming a passage for the quads, &c., said passage being adjustable by employing plates of different thicknesses. In the side plate 27 is a horizontal screw 38, which is parallel with the nipple G, and has its point in the path of the head of the jet of the type, as most clearly shown in Fig. at, so as to penetrate said head while the same is still soft. By this provision the type is pressed against the opposite flange or plate 39 and guided true as it advances on the table. Secured to the side of the table adjacent to the screw 38 are breaking-blocks 40 and 41, the same having inclined faces in reversed directions, the incline of block 40 being on its upper face and that of block 41 being on its under side, (see Figs. 7 and 8,) soas to successively bend the jet in opposite directions as the type is pushed forward and comes in contact therewith, and thus break oif the same from the body of the type. The jet first rides on the incline on block 40, whereby it (the jet) is bent upward, or from the table, and when it reaches the incline on the under side of therblock 41 it is forced downward, or toward the table, so that, owing to the brittleness of the material, it is readily broken off. On the side of the table near the block 38 is a planer 42, for forming the groove or foot in the type as the latter advances on the table. Within the plate 35 is a block 43, which occupies a recess 44, considerably wider than said block, and is held by screws 45, which also occupy slots 46 in the top of said plate, whereby the block is laterally adjustable. The under face of said block is formed with a rib 47, which is raised above the table H, so that as the type passes along, the groove in the side of the same receives said rib, whereby the type is guided true. The block may be set so that the rib may enter a groove at a different point of the side of the type.

J designates a lever which is mounted 011 the bracket 20, and has one end adapted to be engaged by the cam 3 and the other end to come in contact with the arm 5, whereby, should the slide 6 or the plunger 0 stick or bind, said arm is pressed by the lever J, so that the slide is start-ed, the spring 7 then causing the slide to complete its motion. The tension of the spring 7is adjusted by the nut 9 on the rod 8. When the slide completes its return motion, it strikes the screw K, so that said motion is completely stopped at the proper moment, it being seen that said screw provides an adjustment for the return motion of the slide. The arm 5 plays in a slot in the frame A and carries the roller 4, as has been stated, said roller being connected with the arm by means of a screw 4*, whereby it may be adjusted in relation to the face of the pam 1. The upper end of the lever J is provided with the screw L, which provides means for adjusting the distance between said end of the lever and the arm 5.

It will be seen that when the parts are in position, as shown in Fig. 1, the plunger 0 is advanced to full extent and the cam 1 is about to leave the roller 4:, so that said plunger is caused to make its return motion, owing to the action of the spring '7. The slide E is in its lowest or normal position, and the earn 2 is about to reachthe roller 2 on the lever F. As soon as the plunger completes its return motion the slide E is raised, whereby the op posite sides of the casting-chamber 13 are closed by said plunger and slide. A suffi cient quantity of molten metal is now injected into the mold through the nipple G, the same passing through the throat 28 into the casting-chamber 13, thus forming a quad or space. The cam 2 now leaves the roller 2 whereby the lever F, under action of the spring 24, causes the descent of the slide E, thus uncovering the side of the casting-chamber. The cam 1 then reaches the roller 4 and bears against the same, whereby the plunger is advanced and its forward or working end pushes the quad or space through the mold and ejects it therefrom upon the table H. The jet now comes in contact with the block 40, whereby it is bent upward, and then reaches the block 41, whereby it is bent downward, and thus broken off. The quad or space, guided by the block 43 and plate 37, now passes the planer 42, whereby the groove or foot is formed therein, after which the quad or space may be removed or directed elsewhere. In the head 10 isadovetailed or wedge-shaped nut 48, which receives the screw 11, whereby provision is made for releasing the plunger 0 and afterward securing the same in-position, said nut being laterally removable'from said head. The screw K, in addition to acting as a stop for the slide, also admits of adj usting the return motion of said slide, it being evident that various parts of the machine may be removed and substituted by others of larger or smaller size. The extent of descent of the slide E may be adjusted byproviding the stop 16 with a screw 49, which enters the socket 50, whereby said stop may be raised and lowered and the play-of the slide adjusted, so that it may be nicely set at top in relation to the casting-chamber. The planer 42 enters the end of the passage between the plate 35 and table H, and is held in place by an arm a, which is secured to said plate, as will be seen in Fig. 3.

It is evident that by providing a proper matrix in a suitable part of the casting-chamber the machine is adapted for the production of type with letters, figures, &c.
